The edX system keeps track of learners’ progress through a course – recording
when the learner watches videos, responds to problems, and so on. If you are a
member of a course team, some of that data is visible to you for debugging
purposes. Under every problem is a Staff Debug Info button: selecting this
button opens a window with information about the problem.

None of this information should be necessary for day-to-day usage of edX,
but for the sake of clarity, some of these fields are documented here.
